OTHER EXTREME SUB-ZERO OPERATIONS
Lubricants meeting this specification are used in Alaska and
other extreme sub-zero locations. Generally, they may be
described as 5W-20 multigrade lubricants made up of
synthetic base stock and manifesting low volatility
characteristics. Although they have been used successfully in
some severe cold regions, Detroit Diesel Allison does not
consider their use as desirable as the use of SAE-40 or SAE-
30 oils with auxiliary heating aids. For this reason, they should
be considered only where engine cranking is a severe problem
and auxiliary heating aids are not available on the engine.
EMD (RR) OILS
Lubricants qualified for use in Electro-Motive Division (EMD)
diesel engines may be used in Detroit Diesel 2-cycle engines
provided the sulfated ash (ASTM D-874) content does not
exceed 1.000% by weight. These lubricants are frequently
desired for use in applications where both Detroit Diesel and
Electro-Motive powered units are operated. These fluids may
be described as SAE-40 lubricants that possess medium
Viscosity Index properties and do not contain any zinc
Table L-1
additives.
SYNTHETIC OILS
Synthetic lubricants may be used in Detroit Diesel 2-cycle
engines provided the ash limit, zinc requirements, and
specified oil performance levels (for example, CD/SE or MIL-L-
2104B, etc.) shown elsewhere in this specification are met
Viscosity grades SAE-40 or SAE-30 are recommended.
LUBE OIL FILTER CHANGE INTERVAL
Full-Flow Filters
A full-flow filtration system is used in all Detroit Diesel 2-cycle
engines To ensure against physical deterioration of the filter
element, it should be replaced at a maximum of 25,000 miles
for on-highway vehicles. For all other applications, the filter
should be replaced at a maximum of 500 hours.
OIL CHANGE INTERVAL BASED ON SURVEY OF
SATISFIED END USERS
A number of successful Detroit Diesel (2-cycle engine)
Table L-2
customers in numerous service applications do not utilize oil
analysis procedures. They prefer conservative lube oil drain
and filter change intervals.
Lubricant and filters were changed based on experience, and
the customer felt he saved money in eliminating costly lube oil
analysis programs. Naturally, Detroit Diesel supports the lube
oil and filter change practices used in these successful service
operations.
